Triple zone mascara brush

Abstract

A mascara brush having three sections and three types of bristles is disclosed. The brush portion has a larger diameter middle section comprised of a combination of soft and stiff bristles in random configuration, and two end sections comprised of hollow filaments which preferably become progressively shorter towards the ends of the brush portion. The end sections exhibit less bristle density than the middle section. This improved brush configuration allows for optimal one-stroke mascara application.

What is claimed is: 
     
       1. A mascara brush, comprising: a twisted wire core extending longitudinally; and   a plurality of bristles mounted to said twisted wire core, said plurality of bristles comprising a middle cylindrical section containing a plurality of at least first and second different bristle types of relatively uniform length randomly intermingled throughout the length of said middle section and two end sections containing a third type of bristles.   
     
     
       2. A mascara brush according to claim 1 wherein said plurality of bristle types comprises at least one relatively soft bristle type and one relatively stiff bristle type. 
     
     
       3. A mascara brush according to claim 2 wherein the diameter of said middle cylindrical section is at least about 0.325 inches. 
     
     
       4. A mascara brush according to claim 2 wherein at least one of said end sections is tapered, said third type of bristles progressively decreasing in length toward the end of said at least one tapered section. 
     
     
       5. A mascara brush according to claim 4 wherein said middle cylindrical section has greater bristle density than said end sections. 
     
     
       6. A mascara brush according to claim 5, wherein said bristle density in each said section is uniform throughout each section. 
     
     
       7. A mascara brush according to claim 5 wherein said soft bristles are comprised of fibers having a diameter of about 0.001 to 0.002 inches. 
     
     
       8. A mascara brush according to claim 5 wherein said stiff bristles are comprised of fibers of non-circular cross-section having a diameter of from about 0.004 to 0.006 inches. 
     
     
       9. A mascara brush according to claim 5 wherein said end section bristles are formed of hollow filaments of generally circular cross-section. 
     
     
       10. A mascara brush according to claim 9 wherein said end section bristles are comprised of filaments having an outer diameter of about 0.004 to 0.006 inches. 
     
     
       11. A mascara brush, comprising: a tip section terminating at a tip, including first bristles having a first diameter and stiffness;   a middle section adjacent said tip section, said middle section including second bristles having a second diameter and stiffness and third bristles having a third diameter and stiffness, wherein said second and third bristles are blended together in the middle section; and   a base section adjacent said middle section and opposite said tip section, said base section including said first bristles.   
     
     
       12. A mascara brush according to claim 11 wherein said tip section is tapered, with said first bristles of said tip section progressively decreasing in length toward said tip. 
     
     
       13. A mascara brush according to claim 12 wherein said base section is tapered, with said first bristles of said base section progressively decreasing in length toward a base opposite the middle section. 
     
     
       14. A mascara brush according to claim 13 wherein said second and third bristles have a length greater than a majority of said first bristles. 
     
     
       15. A mascara brush according to claim 14 wherein the diameter of said middle section is at least about 0.325 inches. 
     
     
       16. A mascara brush according to claim 15 wherein said middle section has greater bristle density than said tip and base sections. 
     
     
       17. A mascara brush according to claim 16 wherein said second bristles are comprised of synthetic fibers having a diameter of about 0.001 to 0.002 inches. 
     
     
       18. A mascara brush according to claim 17 wherein said third bristles are comprised of synthetic fibers of non-circular cross-section. 
     
     
       19. A mascara brush according to claim 18 wherein said third bristles are comprised of synthetic fibers having a diameter of from about 0.004 to 0.006 inches. 
     
     
       20. A mascara brush according to claim 16 wherein said first bristles are formed of hollow filaments of generally circular cross section. 
     
     
       21. A mascara brush according to claim 20 wherein said first bristles are comprised of synthetic filaments having an outer diameter of about 0.004 to 0.006 inches.
